ОБЩИЕ ВЫВОДЫ

В работе получены следующие основные научные и практические результаты:

1. Проведен анализ современных технологий управления на основе прогнозирующих моделей в перерабатывающей промышленности, в результате чего обоснована возможность применения подходов УПМ.

2. Разработаны типовые структуры систем управления на основе УПМ-подходов. Данные структуры позволяют применять УПМ-подходы в задачах управления системами ККН.

3. На основе исследований физико-химических свойств процесса разработана математическая модель ККН, которая послужила основой для дальнейшего создания редуцированной динамической модели, применяемой в задачах управления на основе прогнозирующих моделей.

4. Получена упрощенная динамическая модель процесса ККН. При разработке структуры данной модели был применен подход Хикка, модифицированный за счет расширения модели путем добавления возмущающих воздействий.

5. Разработана процедура синтеза УПМ-регулятора, которая предоставила возможность реализовывать алгоритмы управления на основе прогнозирующих моделей.

6. Реализован алгоритм управления установкой каталитического крекинга на основе УПМ-регулятора. Результаты моделирования системы управления ККН позволяют сделать вывод об эффективности применения УПМ-подхода.

7. Определены оптимальные параметры УПМ-регулятора. Исследовано влияние настроечных параметров на качество регулирования.

8. Подтверждена эффективность применения УПМ-регулятора для управления технологическим процессом ККН. Проведена апробация предложенных подходов к управлению технологическими процессами ККН. Разработанные алгоритмы использованы в системе управления установкой подготовки нефти УПН-500 (ЗАО НПФ «ИнСАТ»).
